Bovine Tuberculosis Testing Requirements in Georgia: Rules Every Cattle Producer Should Know
August 8, 2026
Georgia cattle producers can move animals across county lines without a single tuberculosis test, yet the moment that same animal crosses a state line, an entirely different set of rules kicks in. Understanding bovine tuberculosis testing requirements in Georgia means knowing exactly when state law, federal law, and herd-level accreditation rules each take over. This matters whether you run a small cow-calf operation, manage a dairy herd, or raise captive cervids for hunting preserves.
Below, you will find a breakdown of how Georgia classifies TB risk, which animals and owners fall under testing rules, which diagnostic tests regulators accept, and what happens if a test comes back positive.
What Is Bovine Tuberculosis and Why It Is Regulated in Georgia
Bovine tuberculosis is caused by Mycobacterium bovis, a bacterium closely related to the pathogen that causes human tuberculosis. Bovine tuberculosis (TB) is a contagious, infectious, communicable disease of animals and humans caused by Mycobacterium bovis, and it is commonly a chronic, debilitating disease that is a widespread zoonosis affecting nearly all species of vertebrates. The disease spreads through direct contact, inhalation of droplets expelled from infected lungs, and ingestion of contaminated feed or milk.
The reason Georgia and every other state regulate this disease so closely traces back more than a century. In 1917, the U.S. Bureau of Animal Industry began the National Tuberculosis Eradication Program due to human and livestock concerns regarding bovine tuberculosis, and it started out as strictly an eradication program for cattle but eventually included both bison and farmed cervids. APHIS and State animal health agencies collaborate with U.S. livestock producers to administer the National Tuberculosis Eradication Program, which has nearly eradicated tuberculosis from the Nation’s livestock population since its inception in 1917.
That success is easy to take for granted. The prevalence of tuberculosis in cattle, bison, and captive cervids is extremely low in the United States, with an estimated prevalence of 7 per 1 million cattle screened. Infected cattle rarely show outward symptoms, which is precisely why testing rather than observation drives the regulatory system. Infected cattle are typically asymptomatic, and detection usually occurs during live animal skin testing or, more commonly, at slaughter through the national slaughter surveillance program.
Pro Tip: If you are moving livestock and want to confirm your trailer meets state inspection standards before a TB test or movement certificate is required, review Georgia’s livestock trailer requirements ahead of transport day.
Georgia’s TB Classification Status and Risk Zones
USDA’s Animal and Plant Health Inspection Service (APHIS) sorts states and zones within states into tiers based on how much bovine TB has been found in local herds. An accredited-free State or zone is defined as a State or zone that complies with the Uniform Methods and Rules, has zero percent prevalence of affected cattle and bison herds, and has had no findings of tuberculosis in any cattle or bison in the State or zone for the previous 5 years. Below that sits the modified accredited advanced tier, then modified accredited, then nonmodified accredited, with each lower tier carrying heavier testing obligations before animals can move interstate.
Georgia’s own rules offer a strong clue about where the state stands. There are no brucellosis or tuberculosis test requirements for intrastate movement of Georgia cattle. That kind of hands-off intrastate policy is only possible in a state that has demonstrated sustained freedom from the disease, consistent with accredited-free status under the federal program.
Not every state maintains a single, uniform classification. Some states carry “split-State status,” meaning one region carries a different risk tier than the rest of the state. The APHIS Veterinary Services Cattle Health Center periodically reviews State tuberculosis programs for States maintaining split-State status or under the conditions of a memorandum of understanding. Georgia currently operates under a single statewide designation rather than separate risk zones, which simplifies compliance for producers moving cattle within the state.
| Classification Tier | General Requirement to Reach Tier | Interstate Movement Impact |
|---|---|---|
| Accredited-free | Zero percent herd prevalence, no TB findings for 5 years | No additional TB testing required to move interstate |
| Modified accredited advanced | Very low prevalence, strong surveillance program | Limited additional testing depending on destination |
| Modified accredited | Prevalence below 0.5 percent of herds | Whole-herd test plus individual test typically required |
| Nonmodified accredited | Prevalence above modified accredited thresholds | Most restrictive testing and movement conditions |
Who Must Test and Which Animals Are Covered in Georgia
Federal rules define which animals fall under the bovine TB program, and Georgia enforces those same categories. The regulated species list is broader than “cattle” alone:
- Cattle and bison of all ages destined for interstate movement or herd accreditation
- Captive cervids, including farmed deer and elk raised for meat, sport, or exhibition
- Goats, which fall under the same Uniform Methods and Rules as cattle and bison
- Herds newly assembled on premises where a previously affected herd was depopulated
Age matters when determining which animals within a herd actually need testing. A whole herd test is an official tuberculin test of all cattle and bison in a herd that are 12 months of age or older, and of all cattle and bison in the herd that are less than 12 months of age and were not born into the herd, except those cattle and bison that are less than 12 months of age and were born in and originated from an accredited herd. In practice, calves born and raised entirely within an already-accredited herd typically skip individual testing during routine herd checks.
Captive cervid owners face a related but distinct set of expectations, since deer and elk are maintenance hosts for the bacteria in parts of North America. In some areas of North America, maintenance species that can carry and shed the bacteria include white-tailed deer, American bison, and elk. If you hold a permit for a deer or elk facility in Georgia, confirm your hunting license and cervid facility obligations line up with herd health testing schedules, since wildlife agencies and animal health officials often coordinate on cervid TB surveillance. Producers should also confirm every regulated animal carries proper identification, since Georgia’s livestock ear tag requirements tie directly into how test records get matched to individual animals.
Approved TB Testing Methods in Georgia
Regulatory veterinarians in Georgia rely on a tiered testing system rather than a single test, because no single tool is perfect on its own. The official tuberculin tests for cattle, bison, and goats are the caudal-fold test, the comparative cervical test, and the cervical test. Captive cervids use a related but separate set of official tests.
The caudal-fold test (CFT) is the standard front-line screening tool. The first test to detect possible carriers of bovine tuberculosis is the Caudal Fold Tuberculin test, in which a small amount of purified protein derivative tuberculin is injected into the fold of skin at the base of the tail; the CFT is read 72 plus or minus 6 hours later, and if negative, no further action is required, but if positive, the animal is classified as a responder and requires further testing. A positive CFT is only a preliminary signal, not a diagnosis. A false positive rate of 1-2 percent is expected during a whole herd test, and responders to the screening test require secondary testing.
When an animal responds to the CFT, a follow-up test confirms or rules out infection:
- Inject the CFT and observe for a delayed hypersensitivity reaction, which typically begins within 8 to 12 hours and peaks around 72 hours after injection.
- Classify any responding animal as a suspect and arrange follow-up testing with a trained regulatory veterinarian.
- Perform the comparative cervical test (CCT) or gamma interferon blood test as confirmation. Follow-up CCT testing must be performed within 10 days of the initial caudal-fold injection in cattle and bison, or the herd owner must wait 60 days after the injection of the CFT before a follow-up CCT can be administered.
- If using the blood-based alternative, submit the sample promptly. If the gamma interferon test is used as a follow-up test, the blood must be drawn within 30 days of the CFT injection date.
- Confirm any reactor result through laboratory culture or histopathology at the national reference lab. Tuberculosis histopathology and bacteriology culture is handled by the National Veterinary Services Laboratories in Ames, Iowa.
Only trained personnel may perform confirmatory testing. The caudal-fold test is used as a presumptive diagnostic procedure, and animals classified as suspect must be evaluated further by the comparative cervical test, gamma interferon test, or sent directly to slaughter under permit, and only Federal or State regulatory veterinarians who have had specialized training may conduct the follow-up testing.
Important Note: Do not schedule other blood draws at the same visit as a TB test. Tail-bleeding is not recommended for other diagnostic procedures, such as brucellosis or Johne’s disease testing, at the time of tuberculin-test injection in cattle or bison because it may interfere with test interpretation. If you also need equine health documentation, keep that testing separate from bovine TB visits — see Georgia’s EIA/Coggins test requirements for horses on the same premises.
Interstate and Intrastate Movement Testing Requirements in Georgia
Movement rules split cleanly along one line: does the animal cross a state boundary? Inside Georgia, the answer is straightforward. There are no brucellosis or tuberculosis test requirements for intrastate movement of Georgia cattle. You can sell, transport, or relocate cattle within the state without a TB certificate, provided no quarantine or disease investigation is already in progress.
Animals coming into Georgia from other states face a different standard. Any animal originating from a state or area where screwworms have become established shall not be transported into Georgia unless the State Veterinarian has issued a prior permit, and all animals entering Georgia for exhibition or consigned to a petting zoo must meet the same interstate movement health requirements as such animals entering Georgia for breeding purposes. Any such animals which develop symptoms of infectious or contagious diseases will be quarantined and permitted directly back to the farm of origin.
Federal rules determine how much TB testing an animal needs before crossing state lines, and that requirement hinges on the TB classification of the state where the animal originated. Cattle or bison that originate in an Accredited-free State or zone may be moved interstate with no restrictions for tuberculosis. Animals from lower-tier states face additional testing. A commuter herd animal moving interstate must be accompanied by a certificate stating that it is from a herd of origin that was negative to an official tuberculosis herd test of all cattle and bison 12 months of age and older conducted within 1 year prior to the date of movement, and that the individual animal was tested negative to an additional official tuberculosis test conducted within 60 days prior to the date of movement.
Because Georgia recognizes rabies documentation, brand inspections, and TB certificates as part of the same movement paperwork bundle, it helps to review your rabies vaccine requirements in Georgia alongside TB rules before hauling animals across state lines. A single incomplete document can hold up an entire trailer load at a checkpoint.
What Happens When a Suspect or Positive Result Occurs in Georgia
A suspect classification triggers immediate reporting obligations, not a quiet wait-and-see approach. If the test produces any type of response, the testing veterinarian must immediately notify APHIS Veterinary Services Area Offices and State animal health officials. All accredited veterinarians must immediately report every suspected or diagnosed bovine TB case promptly to both the Assistant District Director and the State Animal Health Official.
From there, control of the case shifts to specially trained personnel. If the comparative cervical test or gamma interferon test indicates that the animal is a reactor, all further herd testing is conducted by Federal or State regulatory veterinarians. Confirmed reactors typically go to slaughter under a controlled permit so that a full postmortem exam and laboratory culture can settle the diagnosis. This mirrors how officials handle other reportable mycobacterial infections in animals — for comparison, see how avian tuberculosis is diagnosed and managed in poultry and other bird species.
Every reactor and every exposed animal in the herd needs to be tracked individually. All cattle and bison tested must be individually identified by official eartags, and that identification must be recorded in its entirety on the test record at the time of injection and confirmed at the time of observation. This is one more reason accurate ear-tag compliance matters well before a TB investigation ever starts.
Quarantine and Herd Depopulation Rules in Georgia
Once a herd is confirmed affected, officials choose one of two management paths. When health officials find tuberculosis in a herd, it is managed by either depopulating the herd or by testing and removing reactor animals. Neither option is left to the producer’s sole discretion; both proceed under state and federal oversight, and quarantine restrictions remain in place until the herd’s status is resolved.
| Approach | What It Involves | When It Is Typically Used |
|---|---|---|
| Herd depopulation | Removal of the entire herd, followed by cleaning, disinfection, and a waiting period before restocking | Herds with widespread infection or repeated reactor findings |
| Test-and-remove | Reactor animals are removed while the rest of the herd undergoes repeated retesting | Herds with isolated reactors and strong biosecurity controls |
Restocking or adding new animals to a previously affected premises is not a simple return to normal. If any livestock other than cattle or bison are included in a newly assembled herd on a premises where a tuberculous herd has been depopulated, the State or zone must apply the herd test requirements contained in the Uniform Methods and Rules. New individual additions to a herd generally need a documented isolation period. Individual animals added to a herd must be isolated from all other members of the herd of origin and must have negative results on two official tests for tuberculosis conducted at least 90 days apart.
Key Insight: An accredited-free classification for an entire state can be suspended by a single confirmed case. If tuberculosis is detected in any one herd of cattle or bison in an accredited-free State or zone, the accredited-free status of the State or zone is suspended. That is why Georgia’s animal health office treats every suspect result as a statewide compliance matter, not just a single-farm issue.
Penalties for Non-Compliance in Georgia
Georgia treats violations of its livestock health movement rules as a criminal matter, not merely a civil fine. Any person violating the provisions of the interstate movement health requirements chapter shall be guilty of a misdemeanor. The same misdemeanor penalty applies to violations of the intrastate health requirements chapter. That covers moving untested or improperly certified animals, ignoring a quarantine order, or falsifying movement documentation.
Beyond criminal exposure, non-compliance carries practical business consequences. Animals moved without proper certification can be turned back, quarantined at the point of discovery, or ordered destroyed if they originated from or passed through an affected herd. A state’s accredited-free status, and the market access that comes with it, depends on every producer honoring testing and reporting obligations. A single unreported suspect case, left unaddressed, can jeopardize movement privileges for producers across the entire state.
Because these rules intersect state statute, federal regulation, and USDA program standards, specific compliance questions are best directed to the Georgia Department of Agriculture’s animal health section or a USDA-accredited veterinarian rather than general guidance alone. This article summarizes publicly available regulatory sources and does not substitute for a direct compliance determination from your state or federal animal health office.
Pro Tip: Keep copies of every test record, movement certificate, and ear-tag log for at least two years. Federal rules already require states to retain movement certificates for that period, and having your own copies on hand speeds up any future herd accreditation renewal or interstate sale.
Bovine tuberculosis testing requirements in Georgia reflect a system built over more than a century of state and federal cooperation, and the state’s accredited-free-consistent status is the direct result of consistent testing, reporting, and movement compliance by producers. Staying current on ear-tag identification, movement certificates, and herd testing schedules keeps your operation compliant and protects the market access that the entire state’s cattle industry depends on.
